Specification of Letters Patent.

Patented May 11H, 19M.

Original application filed January 15, 1908, Serial No. 410,980. Dividedand this application filed January To all whom it may concern:

Be it known that I, JAMES M. LEAVER, J r., a citizen of the UnitedStates, residing at Sonora, in the county of Tuolumne and State ofCalifornia, have invented a new and useful Gage, of which the followingis a specification.

The present invention, while primarily devised for the purpose of gagingthe length of lumber being sawed," is not necessarily limited thereto,but as will be evident to those skilled in the art, is applicable tocutting, punching, slotting, etc. various materials used in themechanical arts.

The primary object of the invention is to provide gage of a novel andsimple character having a plurality of stops, each of which is movableindependently of the others, and is detachable from its support withoutaffecting the others, so that said gages may be readily adjusted orinterchanged with ease and expedition.

The preferred embodiments of the invention are illustrated in theaccompanying drawings, but it will be evident from an inspection of theclaims hereto appended that said invention is not limited exclusively tothe forms of construction disclosed.

ln the drawings, Figure l is a side elevation of a saw table, showing agage applied thereto and also illustrating the saw. Fig. 2 is a top planview of the same. Fig. 3 is a perspective view of a portion of the baseplate. Fig. (Je is a detail perspective view of a portion of said plate,showing some of the gage stops in place. Fig. 5 is a detail perspectiveview of a slightly modified form of construction. Fig. 6 is an otherembodiment of the invention. Fig. 7 illustrates another form ofconstruction. Fig. 8-11 inclusive are still other modifications of theinvention.

Similar reference numerals designate corresponding parts in all thefigures of the drawings.

Referring to the structure illustrated in Figs. 1-t inclusive, 'the sawtable, which may be of any suitable character, is designated by thereference numeral 1, and a circular saw-2 coperat-es therewith. On thesaw table is mounted a base plate 3, which is provided with alongitudinal slot 4 and transverse slots that communicate with theSerial No. 410,981.

longitudinal slot, and form seats 5 on opposite sides of said slot. Aplurality of ver tically slidable gage stops 6 are mounted in the seatsor transverse slots 5, their upper ends being preferably tapered,4 asshown at 7, the opposite side margins of their lower ends being providedwith recessed seats S. Leaf springs 9, secured at their' outer ends tothe under side of the base plate by screws 10 or other fasteners, havetheir inner free ends curved or coiled, as shown at 11, and detachablyengaged in the seats 8. These springs therefore serve to maintain theupper ends 7 of the gage stops projecting above the base plate, but saidends may be forced downwardly, as will be evident. The gage is used in amanner well understood. The end of a piece of timber is abutted againstthe desired stop, as illustrated in Figs. 1 and 2, and consequently thestops beneath the timber will be depressed, so that they are out of theway. In this construction, each stop can be removed without displacingany of the others, and therefore stops with projections on the sides maybe supplied for gaging fractional lengths. The longitudi nal slot inthis form of the invention is advantageous, in that the stops may beshifted from one of the transverse slots to another without thenecessity of wholly removing the stops from the base plate, the narrowportions between the seats 8 permitting this movement.

The mounting of the stops may be modified in various ways. rl`hus inFig. 5, the base plate 12 has transverse slots 13 therein, in whichvertically slidable stops 111 are located. Beneath the stops is placed asupporting plate 14a, and bowed leaf springs 15, mounted on said plate,have their intermediate portions engaged in seats 1G formed in the loweredges of the stops.

In Fig. 6 the base plate 17 has vertically reciprocating gage stops 18mounted therein, said stops being supported on coiled springs 19, thelower ends of which are located in seats 20 formed in the upper face ofa supporting bar 21.

A base plate 17a is illustrated in Fig. 7, and has a longitudinal slot18a with transverse slots 19a communicating therewith. Verticallyreciprocating gage stops, one of which is shown at 20a operate in thetrans verse slots and are supported on cams 21a journaled on a pivot rod22a located beneath the base plate. The cams have slots 23a that receivethe pivot rod and furthermore have depending arms 24a which carrycounterbalancing weights 25a. In Fig. 8, the base plate 22 hastransverse slots 23, the rear walls of said slots being provided withbearing sockets 24. Vertically swinging' gage stops 25 have lips 26journaled in the sockets, constituting hinge joints. The opposite lowercorners of the gage stops are provided with seats 27, and leaf springs28 secured at their outer ends by fasteners 29 to the under side of thebase plate 22, have their inner ends curved, as shown at 30 and engagein the sockets. The upstanding ends of these gage stops therefore swingdownwardly.

In the structure disclosed in Fig. 9, the base plate 40, has alongitudinal slot 41 with transverse slots 42, forming seats. The baseplate at one side of the longitudinal slot is provided with a dependingflange 48, and slots 44, formed therein, terminate short of the loweredge of said flange, forming a pivot 45. Gage stops, one of which isillustrated at 46 are ournaled on the pivot, each gage stop having anupwardly inclined slotprovided with an enlarged inner portion 47 thatreceives the pivot and a contracted mouth 48 through which the pivot canpass when the gage stop is in an inoperative position. The upper end ofeach stop slides through one of the transverse slots, and projects abovethe base plate. Its lower portion in rear of the depending flange 43,has a seat 49, and a leaf spring 50, secured to the under side of thebase plate, as shown at 51, has a curved inner end 52 engaged in theslot so that the upper end is yieldingly maintained in projectingrelation with respect to the base plate.

In Fig. 10, a base plate, designated 60, has a longitudinal slot 61 andtransverse slots 62 extending on opposite sides of the longitudinalslot. The base plate furthermore has a depending flange 63, the slots 64therein terminating short of the lower edge forming a pivot 65. The gagestops 6G are journaled on the pivot, being provided with slots 67 thatdetachably receive the same. These gage stops operate in the transverseslots 67, and have in their under sides seats 68 in which the curvedfree ends 69 of leaf springs 70 engage, said springs being fastened tothe under side of the base plate 60 by suitable devices 71.

In Fig. 11, the base plate 72 has a longitudinal slot 73 and transverseslots 74.

Swinging gage stops, one of which is illustrated at 75, have slots 76 intheir lower ends that receive a pivot rod 77 located beneath the baseplate. Another pivot rod 78 disposed at one side of the pivot rod 77constitutes a support on which a plurality ol: counterweights 79 aremounted, said counterweights having` slots 80, in which the pivot rod 78is engaged. Each connterwcight has an upstanding ear 81 that bearsagainst the under side of the gage stop 75, and serves to yieldinglyhold the same in elevated position. f

No specific claims are made in this application to the structuiedisclosed in Figs. 7 and 11, inasmuch as they constitute thesubject-matter of another divisional application, tiled simultaneouslyherewith, Serial No. 410,982.

From the foregoing, it is thought that the construction, operation andmany advantages of the herein described invention will be apparent tothose skilled in the art, without further description, and it will beunderstood that various changes in the size, shape, proportion. andminor details of construction, maybe resorted to without departing fromthe spirit or sacrificing any of the advantages of the invention. Inthis connection, it may be stated that this application is subsidiary tocopending application, Serial No. 410,980, and the broad clailns are insaid other application.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

1. In a gage of the character described, the combination with asubstantially horizontal fixed base plate having a longitudinal slot,and transverse slots communicating therewith and forming seats onopposite sides of the longitudinal slot, of a plurality of reciprocatorygage stops slidably mounted in the seats and having their upper endsnormally projected above the base plate, and yieldable means locatedbeneath the base plate and engaging the gage stops for normally holdingthem in an elevated position.

2. In a gage of the character desciibed,v
